title: The correlation between body mass index and intraocular pressure in children.
abstract: OBJECTIVE
  There is evidence from some studies that support an association between obesity in adults and higher intraocular pressure (IOP). However, this association has not been completely studied in children. Our aim is to evaluate the association between child body mass index (BMI) and IOP.
  
  
  METHODS
  Ninety-six children attending the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) in Brazil were studied. Thirty-three were overweight/obese with a mean BMI of 29.7 ± 5.2 and 63 with a mean BMI of 20.8 ± 3.3. IOP was measured using the Goldmann applanation tonometer and was corrected for corneal thickness. The coefficient of correlation between BMI and IOP was calculated.
  
  
  RESULTS
  There was no significant difference in the IOP of children with or without overweight/obesity. The mean IOP was 13.5 and 13.0 mmHg for the right eye and 13.1 and 12.9 mmHg for left eye, respectively (p=0.38 and p=0.71). The results remained the same after correction by pachymetry; 13.0 and 13.1 mmHg for the right eye and 12.4 and 12.9 mmHg for the left eye, respectively (p=0.88 and p=0.41). The coefficient of correlation between BMI and IOP was 0.070 (p=0.496).
  
  
  CONCLUSIONS
  These results do not show a correlation between body mass index and IOP in children. Further studies are warranted to clarify the association between BMI and IOP in children.
